Then, instead of having:

$ ps f -t pts/5

When I run your program, I get:
./foo; ps f -t pts/3
end
PID TTY STAT TIME COMMAND
91677 pts/3 Ss 0:00 -bash
96604 pts/3 R+ 0:00 \_ ps f -t pts/3

I don't see a line corresponding to your '/bin/bash ./foo' line.
Isn't my output what you show in the next example? Is it what was
wanted?
You will have:
$ ./foo
end
$ ps f -t pts/5
PID TTY STAT TIME COMMAND
7287 pts/5 Ss 0:00 bash
20173 pts/5 R+ 0:00 \_ ps f -t pts/5
20172 pts/5 S 0:00 sleep 20
This is what you wanted, right?
